Shortly after the mysterious Cataclysm, one of the scattered survivors walks through what remains of the countryside, carrying both the physical and emotional remnants of his old life through a new, hazardous world.

After managing to find temporary shelter for himself and his ailing daughter, a restless father realizes they are not the only ones roaming the remains of the post-Cataclysm wilderness.

Having survived the winter in a nearly invisible shelter, one of the Cataclysm's few survivors has managed to live off the land and keep his daughter alive. However, every walk into the woods poses a new risk.

Held against his will, a desperate father fights his way out of a high-tech facility run by a mysterious organization that may be hiding clues to what is really happening in the post-Cataclysm world.

As the second winter after the Cataclysm sets in, the lone father finds his resources depleted and health declining. As he makes a trek to seek other survivors, he is led by visions that blur the line between past and present.

Pursued and dying, a father unleashes the very last of his energy to give his daughter one more chance at survival. This concludes the first year after the great Cataclysm.

18 months after The Cataclysm has decimated North America, lone father Alex and his comatose daughter Crystal have settled with a pacifist community that has struggled to maintain a fragile cease-fire with a dangerous militia. The lines begin to shift when someone close to the community reappears after a long absence, bearing news from the outside that could destroy the peace.

After joining the Infinity Group, Danny’s father Dennis reveals that the Firewalker militia has been seizing Sleepers and trafficking these comatose Cataclysm survivors with Allied Command in return for supplies. Learning that Danny’s comatose brother Miles is to be moved between Allied Command facilities, Wallace's community is forced to contemplate a dangerous rescue.

In an act that threatens the cease-fire with the Firewalkers, Alex, Danny and Dennis lead a bold attempt to rescue the comatose Miles from Allied Command captivity.

The Infinity Group has made a major gain, but the cost may prove to be too high. The Firewalkers are scolded by Allied Command for not keeping the regional peace, and are ordered to take drastic measures against Wallace’s community. Meanwhile, as Wallace's community enjoys a rare moment of joy, Alex uncovers a plot that could spark open war with The Firewalkers.
